Abstract
The present invention relates to an imaging system, which comprises a support having a front and rear surface, at least one layer of microcapsules or at least one layer of microcapsules and developer in the same layer or at least one layer of microcapsules and developer in separate layers, on said front surface of the support, wherein the microcapsules or developer or microcapsules and developer are dispersed in a carrier of the invention, said carrier is capable of transferring and adhering developed image and non-image areas from said front surface of said support upon the application of heat energy to the rear surface of the support, said carrier strips from said front surface of the support by liquefying and releasing from said support when heated, said liquefied carrier providing adherence to a receptor element by flowing onto said receptor element and solidifying thereon, said adherence does not require an external adhesive layer, with the proviso that the carrier is not capable of reacting to form an image, and when the microcapsules are present together in the same layer as the carrier, the carrier has a particle size which is the same as or smaller than that of the microca…
